The tower of Evil Dr Em is dark and forboding. A sound of whimpering comes from a cell window
half way up, and from the top you hear the sounds of squeeing.
Evil Dr Em sticks her head out of the upper window and shouts down that she'll tell you how to
become a level three wizard if you bring her 25 stories.

Kill Huge Reptiles to get Plot items (plot point, plot hook, etc). Note that to kill a Huge Reptile you have to spell out one full word per hit point that it has.

Kill Plot Bunnies with the Plot items to get stories. Plot bunnies are primarily found on the Bunny Islets

Collect 25 stories to get a pair of magic underpants from Evil Dr. Em (10 AP). Wear the underpants to become a wizard.

You lose a Pair of Magic Underpants.
The pants sink through your other clothes and fuse permanently with your flesh. After several
minutes they have nearly disappeared except for a distinct blue tint to your nethers. That's
not going to go away, either.

Reptile Spotting

Most often seen on the mountain trail to the City of Lead and Gold and on road/city terrain - however, there have been a number there which are stuck in rock or otherwise intangible even to mages (now removed) so this incidence may be misleading.

They can appear on other planes (like R'1yeh) - Tarot will list them but then fail. Try somewhere else...
